To help popularize the widgets, Yahoo plans will give away the
Konfabulator software that empowers the applications.
Konfabulator had been charging $20 for the software. Anyone who
bought version 2.0 of the software since mid-May will be given
refunds, said Konfabulator CEO Arlo Rose.

I’ve been saying the Konfabulator runtime should be free all along. This is suddenly an interesting competition once again — Konfabulator widgets suddenly have a much larger potential user base than Dashboard widgets. I think this is a great move for Yahoo (and, I hope, a nice payday for the Konfabulator guys).
